Abstract (en)

[origin: EP0265890A2] A method of producing ducts from composite synthetic material, suitable for use as aircraft air intake ducts, whereby a plaster core, first coated with polyvinyl detaching fluid and then flame-coated with a layer of aluminium, is wound with a synthetic-resin-impregnated yarn followed by a carbon-fibre yarn, and, after being oven-cured, is broken out.
